iOS App Store Validation Error

I was attempting to submit an update for Wordballs when I run into an archive validation issue:
iPhone/iPod Touch: Icon.png: icon dimensions (0 x 0) don't meet the size requirements.

The solution ended up being simple enough:
Select Project then go to Build Settings, select All, under Packaging set Compress PNG Files to NO.

I have no idea why this all of a sudden started on my 3rd update, just glad it was simple enough to solve
